In the circuit shown in the figure, the transistors $M_1$ and $M_2$ are operating in saturation. The channel length

modulation coefficients of both the transistors are non-zero. The transconductance of the MOSFETs $M_1$ and $M_2$ are $g_{m 1}$ and $g_{m 2}$, respectively, and the internal resistance of the MOSFETs $M_1$ and $M_2$ are $r_{01}$ and $r_{02}$ respectively.

Ignoring the body effect, the ac small signal voltage gain ( $d V_{\text {out }} / d V_{\text {in }}$ ) of the circuit is

In the MOSFET amplifier of the figure the signal output V₁ and V₂ obey the relationship
